无法在macOS“Big-Sur”和python 3.8中编译pip包：“ld:unknown option:Bsymbolic”

Question

我尝试在Python 3.8 conda环境中的macOS Big Sur上安装Dedalus software

我使用Dedalus作者推荐的script安装了环境

在安装过程中，pip启动的编译失败

有人知道如何解决这个问题吗

于2021年1月15日更新。问题的解决方案是安装clang 11，而不是由conda自动安装的clang 10

Answer 1

从this answer：

The -Bsymbolic flag ... is specific to the GNU linker and platforms using the ELF binary format. OS X uses neither.

我认为您应该报告使用-Bsymoblic标志将Dedalus软件构建为Mac bug

Answer 2

我自己也没有Mac，但为什么不尝试在https://www.python.org/downloads/mac-osx/上下载python 3.9.1呢。我真的不知道这是否会在Big Sur上运行，但是，你可以试试
